ofthe removable type.

The case or clamp a has a recess or opening for the'reception of thetype d1, d2, &c., the bottom of this recess, on which the types rest,being convex, and lined with a strip, b, of rubber or similar elasticmaterial. The ends e f ofthe recess are inclined on radial lines fromthe center of the curve, on which vthe convex bottom of the recess isformed.

The sides of the type .d1 d2, 85e., which are formed of blocks of' woodwith the signs or letters of rubber o r other elastic material, are

inclined to correspond with the convex bottom of the recess, as shown inFigs. l and 3. On one end of each type is formed a projection, g, which,being adapted to a groove, c, in the casing a, prevents the type fromslipping out, an accident which would otherwise frequently happen. Athumb-screw, passing through one end of the case, effectually retainsthe typein position.

I claim as my invention- The combination of the casing a oi' ahandstamp, having a convex' backing for the type, and a groove, o, withthe type, having inclined sides to correspond with the backing, andhaving projections g, substantially as described.-

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g Witnesses.
